Answer:
the correct answer is (b) low specific heat
Rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.
The largest displacement of sound wave constituents from their resting positions is referred to as amplitude. It stands for the loudness or intensity of a sound, to put it simply. Here are some illustrations of both high and low-amplitude sounds:
High Amplitude Sound: An illustration of a high amplitude sound is a rock concert with loudspeakers blaring songs at full intensity. The concert speakers produce sound waves with a tremendous amplitude, creating a powerful, strong sound that can be heard from a great distance.
Low Amplitude Sound: A low amplitude sound is something like the sound of a whisper. The sound created when someone whispers is calm and soft and not as loud as a rock concert, since the sound waves produced have a tiny amplitude.
In both cases, how loud or soft the sound is perceived by our ears depends on the amplitude of the sound waves. Low-amplitude sounds are soft and quiet, but high-amplitude sounds are strong and loud.
Hence, rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.

Answer:
option C first gear
Explanation:
we know car is parking in uphill
so is we park park on neutral it will free move that is damage car
so we park car on uphill in first gear and turn wheel away from kerb
and park car on downhill in reverse gear and turn wheel toward kerb
so any gear may be reverse or first
so correct option is C first gear
